Table 1. Overview of SOuRCe subscales.

Subscale	Level	# items	Description constructs measured
RCR Resources	Institutional	6	degree to which respondents perceive the existence of effective educational opportunities about RCR, available policies and professionals to whom concerns can be addressed, and leaders who actively support RCR
Regulatory Quality	Institutional	3	factors such as the degree to which regulatory committees such as the Medical Ethical Testing Committee treat researchers fairly.
Integrity Norms	Departmental	4	degree to which norms about research integrity exist in one’s department.
Integrity Socialization	Departmental	4	degree to which organizational departments engage in activities that effectively socialize junior researchers in research integrity.
Supervisor/Supervisee Relations	Departmental	3	relations between supervisors and their supervisees in terms of fairness, availability and respect
(Lack of) Integrity inhibitors*	Departmental	6	degree to which conditions like lack of adequate resources or suspicion and competition between colleagues produce difficulties for conducting research responsibly.
Expectations	Departmental	2	degree to which the department’s expectations for publishing and obtaining external funding are fair

Columns stipulate level of measurement, number of items per subscale and a description of the constructs that subscale measures.

*This scale was reversely scored so that all subscales can be interpreted using the same logic (i.e. a higher score means a greater lack of inhibiting factors, which indicates a better research integrity climate).
